Awesome game, the best one I have played so far in the whole jam, congrats man, I'm amazed you did such a polished game alone on only 10 days, improve it, add features and for sure you can put on steam.
Some improvements I think could improve the game, add some actions to the rooms when opening it, the enigmas are fun but maybe having some sort of giants spiders to fight, mummies (or what not) could make more alive, like defeating some enemies that would drop some thing to light the first laser.
Footsteps sounds are a bit out of sync.
also I got stuck some times, but is totally normal for the time you had to test the game, adding a screen shot here where I got stuck I few times and had to press E to lose control move a bit and press E again to start moving the stone:
